GEORGE HARRISON LAUB, OF WEST LEBANON, INDIANA.

PUMP.

SPECIFICATION forming part of Letters Patent No. 379,233I dated March13. 1888.

Application filedAplil 27, 1887. Serial No. 236,379. (No model.)

To @ZZ whom, it may concern:

Be it known that l, GEORGE HARRISON LAUE, a citizen of the UnitedStates, residing at Vest Lebanon, in the county of Varren and State ofIndiana, haveinvented certain new and useful Improvements in Pumps; andIdo declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in lifting-pumps, which will befully understood from the following description and claims when taken inconnection with the annexed drawings, in which Figure l is a sideelevation of myimproved suction or lifting pump sustained in a well,which is represented in section. Fig. 2 is a vertical section throughthe pump. Fig. 3 is a vertical transverse section through the upperflattened tapering portion of the pump and the cone-packing on the lowerend of said tapered portion. Fig. 4 isa vertical section through thepump-bucket and the lower part of the rod therefor. Fig. 5 is aperspective View of the coupling for the two cylinders and the twoSuspenders, detached from said parts. Fig. 6 is a sectional detail ofthe pump-bucket, it being a modification showing an upwardlydaringcupped wedge or box adapted to afford bearings for the daps m m whenopen or in the act of depressing the bucket.

Referring to the drawings by letter A A designate the twoverticallydivided halves which constitute the casing for the upper partof the pump, and which are usually made of wood. These halves areadapted to rest upon the platform at the upper end of the well and toprotect the pump from extremes of temperature. The said halves of thecasing are preferably secured together by means of dowelpins, a yoke, a,and key-pins et', and provided with a suitable cover, which is removablewhen desired.

The half A of the said casing has depending from and rigidly secured toit a bar, B, usually made of wood, which suspends the pump in the well.This bar B may be of any desired length, depending in some instancesupon the depth of the well.

C designates the pump-cylinder proper, in

which works vertically the pump -bucketg and D designates a metalliccoupling or foot, which is cast hollow. To a sheath, b, of this couplingis rigidly secured the lower end of The upper hooked ends of 6ohorizontal water passage, cl, which communi- Cates with the lower end ofthe cylinder C and also with the upper end of a penstock, E. The upperend of this penstock, or the upper section thereof, (ifit be composed ofmore than one section, as showin in Figs. l and 2 of the drawinga) isfitted water-tight into a socket, e, formed about the inlet-passage forwater. The penstock E is firmly held to the coupling D by means of alongstirrup-shaped rod, which is passed through a perforated and flangedstep, e, at the lower end of the penstock, through ears formed on thesides of the coup-l ling, and secured by keys, screws, or theirequivalents.

At the upper end of the induction waterpassage inside of the coupling Dis a fiat valveseat adapted to a valve, f, leathered on its bottom, andconnected by ears and a V-shaped link to a cap, g, which is adapted toclose water-tight the end of the horizontal part of the coupling, andwhich is removably secured in place thereto by means of hookedfastenings h h', er their equivalents, attached pivotally to ears formedintegral with the said coupling. In addition to the bolt-fastening ac,for securing the cylinder G to the coupling D, this cylinder is securedto the depending bar B by a staple, i, which passes through the latter,and is locked by means of a key,

In addition to the stirrup-fastening for the penstock E, abovedescribed, this penstock is secured to a vertical supporting-bar, vG, bymeans of a band, j, the perforated ends of which pass through said barand are secured thereto by a key. This vertical bar G is rigidly securedto a sheath, k, formedintegral with ICO' the coupling D, and this bar isadapted to support the pump upon the bottom of the well when necessary.

H designates a cylindrical hollow pumpbucket, the lower part of whichpresents two inclined planes, ZZ, which are perforated for the freepassage of water during the descending strokes of the bucket. Inside ofthis bucket, and suitably hinged at its angular lower end,arebutterliy-valves m m, and above these valves is a spider, m', and anannular or cupped packing, m2.

J designates the pump-rod, which may be jointed in the usual manner tothe pump-handle K, having its fulcrum in the halfA of the pump-casing.The lower end of this rod J has an angular strap, p, secured to it,through the lower end of which passes a headed screw,

g, that passes through the lower angular end of the pump-bucket H, andreceives a nut on it. By these means the pump-bucket is rigidly butremovably secured to the pump-rod.

L designates an upwardly-Haring cylindercap, which is preferablyflattened, as shown in the drawings, and which is provided with adischarge-spout, S, leading through the casing AA. Thiscylindercap orextension may be of any desired length, and it is provided on its lowerend with a rigidly-attached tapering packing-plug, t, confined betweenflanges u u, and fitted water-tight into the upper end of the cylinder.

Vertically through the packing-plug t and its upper iiange is anaperture, n, provided with a removable plug, w.

It will be observed that all of the working parts of my improved pumpare accessible for the purpose of repair.

l nstead of tapering the bottom of the bucket H to a point, as shown inFig. el, I horizontally flatten the bottom, as shown in Fig. 6, thusforming an inverted frustuin of a cone.

Inside of this cone I use an upwardly-flaring cup, H', adapted to affordbearings for the valves or aps m m, when in the position indicated insaid Fig. 6, during the act of depressing the bucket.

Having described my invention,what I claim as new, and-desire to secureby Letters Patent, 1s-

l. In a lifting-pump, the combination, with a vertical divided casing,of a vertical bar depending therefrom, a hollow coupling secured to thisbar, a pump-cylinder secured to said coupling and having a valved bucketin it, a penstock also secured to said coupling, a flap-valve removablyapplied therein at the upper end of the penstock, and an upwardly-Haring conduit provided with a dischargespout, all substantially asdescribed.

2. The combination of a hollow coupling provided with sheaths b k, a datvalve-seat, a socket for the cylinder C, a socket for the penstock E, aremovable cap, a valve linked to this cap, and a suitable fastening forthe same, substantially as specified.

3. The combination of the hollow coupling D, the cylinder C, fitted intothis coupling, the depending bar B, secured to the coupling and saidcylinder, the penstock E, fitted into the coupling, the supporting-barG, secured to the latter and also to the penstock, the removable cap g,and a valve linked to this cap,

substantially as specied.

4. The combination of a pump-bucket hav? ing inclined flattened andperforated sides ZZ, an upwardly-daring cup centrally arranged in saidbucket, the hinged Hap-valves, the packing and spider, and thebucket-rod, all substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
